Abstract A lock bolt operating handle assembly having a pan-shaped housing unit presenting front and back face portions in spacedapart planes and a closed exposed front surface. A lock bolt engaging and operating member is located rearwardly of the exposed front surface and projects through the plane of the back face portion. Arm means pivotally mount the operating member in the housing unit on an axis intermediate of the planes of the front and back face portions and project through the exposed front surface. A handle, normally lying intermediate of the planes of the front and back face portions, is secured to the arm means forwardly of the exposed front surface for effecting pivotal movement of the arm means and the operating member.
